Special tools, testers and auxiliary items required 

NOTE:
  • All bolts at suspension parts with bonded rubber bushings must always be tightened in curb weight position (unloaded condition).

Bonded rubber bushings have a limited torsional range.

Parts with bonded rubber bushings must be brought into a position that corresponds to the position in driving mode before being tightened (curb weight position)

Otherwise, bonded rubber bushing will be stressed resulting in a shortened service life.

By raising appropriate suspension using engine/transmission jack V.A.G 1383 A and Wheel Hub Support T10149 , this position can be simulated on the hoist.

The measurement must be taken in curb weight position (unloaded). 

Before appropriate suspension is raised, vehicle must be strapped to lift arms of hoist using tensioning straps T10038.

If a vehicle is not secured, there is danger that the vehicle could slip off the lift!

Tightening of the respective bolts/nuts must then only occur after dimension - a - , which was measured before installation between the wheel hub center and the lower edge of wheelhousing, has been attained 

CAUTION:
  • Do not lift or lower vehicle with engine/transmission jack below vehicle.
  • Do not leave engine/transmission jack V.A.G 1383 A below vehicle any longer than necessary.
